Evening Must-Read: Simon Wren-Lewis: Fighting the Last War
…Why is it illegal in the Eurozone? The answer is a fear that if you allow governments access to the printing presses, high inflation will surely follow at some point. Many of those who worry about helicopter money are fairly relaxed about Quantitative Easing (QE), which involves much more money creation than would be involved in a helicopter drop…. The key reason they are more relaxed is that central banks are in control of QE, whereas governments would initiate money financing of deficits…. I think it is possible to take two quite different views…. The first is that, in most OECD economies today where macroeconomic understanding is better and information more available, inflation targets are more than sufficient to prevent us experiencing the inflation rates of the 1970s again….
A second view is that we have the story of the 1960s and 1970s all wrong. We did not get high inflation in advanced economies because governments wanted to monetise their own profligacy… [but] because of the combination of a number of specific factors: trade union pressure in the face of shocks that tended to reduce real wages, underestimation of the natural rate (and a poor understanding of how monetary policy should work), and placing too great a priority on achieving full employment. The latter might have been a legacy of the 1930s: policymakers were also fighting the last war…. I think both views are probably correct. As a result, I’m much more relaxed about money financing of deficits in the current situation…. However, irrational fear of rising debt in a recession has similar characteristics to fighting the last war: deficit bias is a problem, but a recession is not the time to worry about it. I think this is why I am not persuaded by this article by Ken Rogoff: yes, in the grand scheme of things we should worry about inflation and debt, but right now we are worrying about them too much and therefore failing to deal with more pressing concerns.
